From the information given;
P(cold) = 0.4
P(no cold) = 1-0.4 = 0.6

The number of ways of selecting 4 from 10 = 10C4 = 210

Probability that the 4 selected with catch a cold:

P(4 will catch cold) = (10C4)*P(cold)^4*P(no cold)^6 =  210*0.4^4*0.6^6 = 0.2508

Answer:

  m∠Y = 40°

Step-by-step explanation:

The sum of complementary angles is 90°. If we let s and y represent m∠S and m∠Y, respectively, the angle measures in degrees satisfy ...

  s + y = 90

  (4y -110) +y = 90 . . . . . . . . substitute for s

  5y = 200 . . . . . . . . . add 110

  y = 40 . . . . . . . divide by 5

The measure of angle Y is 40°.

We know that
[volume of the prism]=L*W*H
L=x²*y in
W=x in
H=y² in

[volume of the prism]=(x²*y)*(x)*(y²)-----> x³*y³ in³

the answer is
x³*y³ in³
